search for: ib_empty

I'm running on Sun Blade 2500 with a GeForce 8400 GS PCI. After (maybe?) fixing a few errrors with bo allocation, I'm getting a lot of IB_EMPTY errors, ultimately resulting in a GPU lockup. I don't have any sort of framebuffer visible. After reading dma-pusher.txt, I see "An attempt to submit IB entry with length zero will raise DMA_PUSHER error of type IB_EMPTY." How would an empty command be generated? Here is the result...

Hi everyone. I'm a big Free Software enthusiast and, therefore, I would very much like to use the nouveau free driver, instead of the proprietary one. My problem is that, looking for the cheapest option available, when I needed to buy a new graphics card, 2 years ago, I decided for a model from a brand that I had never heard of - called "Gainward" - because I thought it had a
